AMERICAS SILVER CORPORATION PROVIDES AN UPDATE ON THE SAN RAFAEL PROJECT

TORONTO–(BUSINESS WIRE)–Sep. 11, 2017– Americas Silver Corporation (TSX: USA) (NYSE “MKT”: USAS) (“Americas Silver” or the “Company”) is pleased to provide an update on its 100% owned San Rafael Development Project, part of the Cosalá Operations in Sinaloa, Mexico.

Based on the April 2016 San Rafael Technical Report (the” Report”), the Company targeted initial production to be sourced from the southern lobe of the Main Zone while development of the primary ramp continued toward the larger and more massive part of the deposit further to the north. Development towards this southern lobe began in January 2017 and ore is now being mined from two development headings in this area with two levels being prepared for production. Ore from three additional headings will be added to the existing surface stockpile within the next week.

The primary ramp which will provide long term access to the bulk of the deposit is progressing well. Approximately 480 meters of additional development is required before the main drive reaches the bottom level of the Main Zone. The schedule calls for this work to be completed over the next seven to nine months.
